Phenomenon
Trouble Shooting
Indoor unit does not
operate immediately
when the air condi-
tioner is restarted.
Once the air conditioner is stopped, it will not oper-
ate in approximately 3 minutes to protect itself.
There’s unusual
smell blowing from
the outlet after op-
eration is started.
This is caused by the odors in the room which have
been breathed into the air conditioner.
Sound of water
flow can be heard
during operation.
This is caused by the refrigerant flowing inside the
unit.
Mist is emitted dur-
ing cooling operation.
Because the air of the room is cooled down rapidly
by the cold wind and it looks like the fog.
Creaking noise can
be heard when start
or stop the unit.
This is caused by the deformation of plastic due to
the change of temperature.
Air condi-
tioner does
not operate
at all.
Has the power been shut down?
Is the wiring loose?
Is the leakage protection switch in operation?
Is voltage higher than 242V or lower than 198V?
Is TIMER ON in operation?
Cooling (Heating)
efficiency is not
good.
Is SET TEMP. suitable?
Is air inlet or outlet obstructed?
Are air filters dirty?
Is indoor fan speed set at low speed?
Is there any other heat sourse in your room?
Wireless remote
controller is not
available.
Is the remote control unit out of effective distance
to the indoor unit?
Replace the worn batteries of wireless remote con-
troller.
Are there any obstructions between the wireless
remote controller and the signal receptor?
